Tool/software:
With the DAC11001 converter, the reference circuit is only bipolar, and we only use unipolar now, what kind of modifications can be made to the circuit? Or there is a reference circuit available. If the output is unipolar, does the code need to be configured specially? In addition to the above hardware changes. At present, we are trying to connect the op amp of the negative voltage reference of the bipolar reference to ground in phase, and the circuit does not work properly, or we can help provide the schematic diagram of how to change the unipolar operation of the DA（The actual circuit only uses outputs greater than zero volts, but AD is a bipolar reference power supply, so I can only use half of it, which is 19 bits, and I want to use 20 bits now, so please ask me how to implement the unipolar configuration of Da）,Thanks
